k3

The k3 attribute defines one of the values to be used within the the arithmetic operation of the <feComposite> filter primitive.

The pixel composition is computed using the following formula:

result = k1*i1*i2 + k2*i1 + k3*i2 + k4

Only one element is using this attribute: <feComposite>

<svg viewBox="0 0 420 200" xmlns="http://www.w3.org/2000/svg">
  <filter id="composite1" x="0" y="0" width="100%" height="100%">
    <feComposite in2="SourceGraphic" operator="arithmetic" k1="1" k2="0" k3="1" k4="0" />
  </filter>
  <filter id="composite2" x="0" y="0" width="100%" height="100%">
    <feComposite in2="SourceGraphic" operator="arithmetic" k1="1" k2="0" k3="10" k4="0" />
  </filter>
